Foreigners often make some strange mistakes in Chinese when they study the most difficult language--- ---Chinese. We try to analyze typical sentences to correct these errors.
Tāmen liǎnɡɡè jīntiān wǎnshɑnɡ yě dònɡshēn.
False: 他们俩个今天晚上也动身。
Tāmen liǎnɡ jīntiān wǎnshɑnɡ yě dònɡshēn.
True: 他们俩今天晚上也动身。
俩的意思是两个。既包含数词“两”，又包含量词“个”。俩的后面不能再接个或者其他量词。
俩refers to 两个. As the combination of the numeral 两 and the measure word 个, it can not be followed by any measure word including 个.
